The three most common types of switched networks are circuit-switched and pack- switched networks and heterogeneous switched network

True

False

The Dynamic Host Configuration Protocol (DHCP) helps IP to get the network-layer address for a host.

True

False

In a coaxial cable, One of the wires is used to carry signals to the receiver, and the other is used only as a ground reference. The receiver uses the difference between the two. The unwanted signals are mostly canceled out.

True

False

An RFC is labeled required if it must be implemented by all Internet systems to achieve minimum conformance.

True

False

Using polling protocol means that all data exchanges must be made through the primary device even when the ultimate destination is a secondary device.

True

False

In time-domain representation, changes in signal over a short span of time means high frequency whereas change over a long span of time means low frequency.

True

False

In the 1-persistent approach, when a station finds an idle line, it waits 1 second then send the packet.

True

False

Attenuation in fiber-optic cable is flatter than twisted-pair cable and coaxial cable. Therefore, we need fewer repeaters than twisted-pair cable and coaxial cable.

True

False

A main consideration in the evolution of Ethernet was to keep the MAC sublayer untouched.

True

False

In a wireless LAN, the host needs to be physically connected to the Internet to use its services

True

False

The DSL service also allows the line to be used simultaneously for voice and data communication.

True

False

Typically, when a host moves from one LAN to another?

Both MAC and IP address change

MAC address does not change and IP address changes

Nothing changed

MAC address changes and IP address does not change
